I set my 1TB USB3 external Buffalo HD to be able to boot up several ISO's in the first partition called Utilities, there are 6 more 4GB partitions for Vista32, Vista64, W732, W764, W832 and W864. I could boot from any of my ISO's or do an install of any of the OS's and it worked great. I used Parted Magic to create the partitions and then EasyBCD ver 2.0.2 for the boot menu. I updated to EasyBCD 2.2 and didn't seem to have any trouble and was able to make changes and not have any problems. Not sure what I did but I screwed it up, and I haven't been able fix it or recreate it. No problem with the ISO's, but when it comes to the OS's I'm stuck. What I need it to look like is (example) Device:[H]\sources\boot.wim with each of the OS's having it's own device letter, but it's just not putting that in anymore. I'm not sure what I'm doing wrong.
